If with Potentiometer: Arduino Course 5.3

This lesson expands on the use of if-else statements in programming, demonstrating how to handle multiple conditions using a potentiometer and LEDs. The tutorial covers setting up a circuit, writing a sketch, and implementing if-else logic to control LEDs based on sensor values. It emphasizes the importance of testing and verification, and provides advanced examples of using multiple conditions. The lesson concludes with recommendations for effectively using if-else statements.

What is the purpose of using multiple if-else statements in programming?

How does a potentiometer mimic the output of an analog sensor?

Explain how the analog read function works with a potentiometer.

Describe the significance of using global variables in the sketch.

What are the conditions checked in the if statement for turning on the LEDs?

What happens when the sensor value is below 100 in the code?

How can you improve the code by avoiding hard-coded numbers?

What is the role of the else if statement in the code?

Explain the use of Boolean operators in the conditional statements.

What is the purpose of the default else statement in the final code?
